Description

Decoupling method and device of multi-energy coupling system, electronic device and storage medium
Technical Field
The present disclosure relates to the field of multi-energy coupling systems, and in particular, to a decoupling method and apparatus for a multi-energy coupling system, an electronic device, and a storage medium.
Background
The multi-energy coupling system is an energy system which couples a plurality of energy sub-networks in different energy forms with each other and realizes energy complementation among the sub-systems through a reasonable scheduling mode, and is generally called as an integrated energy system. A common multi-energy coupling system comprises a plurality of energy sources such as electricity, heat, cold, gas, etc., each energy source can exist in the multi-energy coupling system in the form of one or more energy sub-networks, and each sub-network can also be coupled with one or more sub-networks in different energy forms.
In order to obtain the working conditions of the electrical subsystem, the thermal subsystem, the cold subsystem, the gas subsystem and the like in the multi-energy coupling system (for example, the working conditions may include, but are not limited to, the voltage amplitude and the phase angle of the node of the electrical system, the gas pressure and the branch flow of the node of the natural gas system, the temperature of the supply and return water of the node of the thermodynamic system, the mass flow of the hydraulic system and other state variables), simulation calculation is required.
At present, existing simulation calculation methods are divided into two main categories: a unified iterative method and an alternating iterative method.
The unified iterative method needs to establish the state equations and the coupling relations of all the subsystems and uses the augmented Jacobian matrix to carry out unified iterative solution, and the method needs to establish equations with different dimensions and time scales, so that the solution efficiency and the stability of the equations are not good. After the alternate iteration method passes through the given coupling state, each subsystem independently calculates the energy flow, and corrects the given value of the coupling state according to the calculation result until the change of the given value of the coupling state is smaller than the given threshold value.
The inventor researches and discovers that when simulation calculation is carried out based on an alternating iteration method, the complex coupling relation and the characteristic difference of different energy networks in the multi-energy coupling system bring great difficulty to the simulation calculation, for example, the balance of each subsystem needs to be judged artificially according to the composition (composition) condition of an equation set or the network coupling relation, which causes the problem of inconvenient decoupling operation (simulation operation).

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1, a schematic diagram of the coupling relationship of a multi-energy coupling system is provided. The multi-energy coupling system is formed by coupling 4 subsystems, the calculated variables of each subsystem, the coupling relation with other networks, the known quantity and the unknown quantity are shown in the figure (wherein the variables of the subsystem 1 comprise F1, F2, F3 and F4, 4 variables in total, the variables of the subsystem 2 comprise P1, P2, P3, P4 and P5, 5 variables in total, and the variables of the subsystem 3 comprise P1, P2, P3, P4 and P5Φ1、Φ2、Φ3、Φ4 andΦ5, 5 variables in total; variables of the subsystem 4 includeθ1、θ2、θ3 andθ4, 4 variables in total. And based on the difference of the subsystems, the types of the corresponding variables may be different, such as the node voltage amplitude and the phase angle in the electrical system, the node air pressure and the branch flow in the natural gas system, the node supply and return water temperature in the thermodynamic system, and the flow in the hydraulic system, etc., which are not specifically limited herein), it should be noted that the unknown quantities of the system must satisfy: the number of unknowns = number of subsystems + number of coupling equations.
For the above-mentioned multi-energy coupling system, if the existing alternative iteration method is adopted, first, the balance of each subsystem needs to be artificially identified according to the known quantity and the coupling equation (for example, the balance of the subsystem 1 isF 2The balance of the subsystem 2 isP 4The balance of the subsystem 3 isΦ 1The balance of the subsystem 4 isθ 1) Obviously, this has certain difficulty, so that the decoupling operation is inconvenient, and when the network coupling relationship is more complex, the method of artificially identifying the balance amount is almost impossible.
In order to solve the above technical problem, embodiments of the present application provide a decoupling method and apparatus for a multi-energy coupling system, an electronic device, and a storage medium, which are described below.
In conjunction with fig. 2, an embodiment of the present application provides an electronic device 10 that may include a memory 12, a processor 14, and a decoupling apparatus 100 of a multi-energy coupling system.
Wherein the memory 12 and the processor 14 are electrically connected directly or indirectly to realize data transmission or interaction. For example, they may be electrically connected to each other via one or more communication buses or signal lines. The decoupling means 100 of the multi-couplable system comprise at least one software functional module which can be stored in the form of software or firmware (firmware) in the memory 12. The processor 14 is configured to execute an executable computer program stored in the memory 12, for example, a software functional module and a computer program included in the decoupling apparatus 100 of the multi-energy coupling system, so as to implement the decoupling method of the multi-energy coupling system provided by the embodiment of the present application.
Alternatively, the Memory 12 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Read-Only Memory (EPROM), an electrically Erasable Read-Only Memory (EEPROM), and the like.
The processor 14 may be a general-purpose processor including a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), and the like.
It will be appreciated that the configuration shown in FIG. 2 is merely illustrative and that the electronic device 10 may include more or fewer components than shown in FIG. 2 or may have a different configuration than shown in FIG. 2. For example, the electronic device 10 may further include a communication unit for information interaction with other devices.
With reference to fig. 3, an embodiment of the present application further provides a decoupling method of a multi-energy coupling system applicable to the electronic device 10. Wherein. The method steps defined by the flow related to the decoupling method of the multi-energy coupling system may be implemented by the electronic device 10.
The specific process shown in fig. 3 will be described in detail below.
Step S110, obtaining the degree of freedom of each subsystem included in the multi-energy coupling system.
In this embodiment, when the multi-energy coupling system needs to be coupled (simulation calculation), the electronic device 10 may obtain the degree of freedom of each subsystem included in the multi-energy coupling system, so that a plurality of degrees of freedom may be obtained.
Wherein the multi-energy coupling system comprises a plurality of subsystems and the degrees of freedom may be determined based on a number of unknowns of the corresponding subsystems.
Step S120, among the plurality of subsystems, determining at least one first target subsystem based on the degrees of freedom.
In this embodiment, after acquiring the degree of freedom of each subsystem based on step S110, the electronic device 10 may determine at least one subsystem from the plurality of subsystems based on the degree of freedom, and thus may obtain at least one first target subsystem.
Step S130, solving the balance quantity belonging to the unknown quantity in each first target subsystem, and updating the degree of freedom of each first target subsystem based on the solving.
In this embodiment, after determining the at least one first target subsystem based on step S120, the electronic device 10 may perform, for each first target subsystem, a solving process on a balance belonging to an unknown quantity in the first target subsystem. In this way, the value of the balance amount, which is changed from an unknown amount to a known amount so that the known amount of each first target subsystem changes, can be obtained, and the degree of freedom of each first target subsystem can be updated in consideration of the fact that the degree of freedom of the subsystem is determined based on the corresponding known amount.
Step S140, determining that the decoupling of the multi-energy coupling system is completed when the degrees of freedom of the subsystems meet the preset conditions based on the updated degrees of freedom.
In this embodiment, after performing solution processing on the balance amount and update processing on the degrees of freedom based on step S130, the electronic device 10 may determine whether the degrees of freedom of the plurality of subsystems satisfy the preset condition based on the degrees of freedom after the update processing. Thus, when the degrees of freedom of the plurality of subsystems meet a preset condition, it can be determined that the decoupling of the multi-energy coupling system is completed.
Based on the method, the degree of freedom determined by each subsystem in the multi-energy coupling system based on the unknown quantity is obtained, so that the target subsystem can be determined based on the degree of freedom, and then the balance quantity in the target subsystem is solved, so that the decoupling of the multi-energy coupling system can be completed. Therefore, the balance quantity can be solved based on the degree of freedom of the subsystems, so that the balance quantity of each subsystem is not judged manually according to the composition (composition) condition of an equation set or a network coupling relation, and the problem of inconvenient decoupling operation in the prior art is solved.
In the first aspect, it should be noted that, in step S110, a specific manner of obtaining the degree of freedom of the subsystem is not limited, and may be selected according to actual application requirements.
For example, in an alternative example, the number of unknown quantities in the subsystem may be obtained first, and then a corresponding mapping is performed based on the number to obtain the degree of freedom of the subsystem, such as the degree of freedom increases and decreases as the number increases.
For another example, in another alternative example, in order to enable the degree of freedom to sufficiently reflect the number of unknown quantities in the corresponding subsystem, in conjunction with fig. 4, step S110 may include step S111 and step S112, which are described in detail below.
And step S111, determining the number of the unknown quantities in each subsystem of the multi-energy coupling system.
In this embodiment, when the multi-energy coupling system needs to be coupled (simulation calculation), the number of unknowns in each subsystem in the multi-energy coupling system may be determined. Thus, for multiple subsystems, multiple numbers are available.
Step S112, the number of unknowns in each of the subsystems is used as the degree of freedom of the subsystem.
In this embodiment, after obtaining the number of unknown quantities in each subsystem based on step S111, for each subsystem, the number of unknown quantities in the subsystem may be directly used as the degree of freedom of the subsystem, for example, if the number of unknown quantities in one subsystem is 0, the degree of freedom of the subsystem is 0; the number of unknowns in a subsystem is 1, then the degree of freedom of the subsystem is 1.
Alternatively, the specific manner of performing step S111 to determine the number of unknowns in the subsystem is not limited, and may be selected according to the actual application requirements.
For example, in an alternative example, for each subsystem, the parameters (i.e., unknown quantities) currently having an indeterminate value in the subsystem may be directly counted, and the number of unknown quantities in the subsystem may be obtained.
For another example, in another alternative example, in order to improve the efficiency of the subsequent calculation and ensure that the decoupling can be effectively completed, in conjunction with fig. 5, step S111 may include step S111a, step S111b, step S111c, and step S111d, which are described in detail below.
Step S111a, forming an unknown quantity set based on the unknown quantities included in each subsystem of the multi-energy coupling system, and obtaining a plurality of unknown quantity sets.
In this embodiment, for each subsystem in the multi-energy coupling system, a set of unknowns may be formed based on the unknowns included in the subsystem (it is understood that, based on different requirements, in some examples, the known quantities included in the subsystem may not be processed, and in other examples, the set of known quantities may be formed based on the known quantities included in the subsystem). Thus, for multiple subsystems, multiple sets of unknowns may be obtained.
Step S111b, for each unknown quantity set, determining whether a target unknown quantity exists in the unknown quantity set based on a system coupling equation included in the multi-energy coupling system.
In this embodiment, after obtaining a plurality of sets of unknowns based on step S111a, for each set of unknowns, it may be determined whether a target unknowns exists in the set of unknowns based on a system coupling equation included in the multi-energy coupling system.
Wherein the target unknown quantity and the at least one known quantity are related based on at least one of the system coupling equations. For example, there is a system coupling equation that can be expressed as a representation of the target unknown quantity and a known quantity.
Step S111c, for each unknown quantity set in which the target unknown quantities exist, removing the target unknown quantities in the unknown quantity set, and taking the number of unknown quantities in the unknown quantity set after removal as the number of unknown quantities of the corresponding subsystem.
In this embodiment, after determining whether the target unknown quantity exists based on step S111b, if the target unknown quantity exists, for each set of unknown quantities in which the target unknown quantity exists, a removal process may be performed on the target unknown quantity in the set of unknown quantities (i.e., the target unknown quantity is removed from the corresponding set of unknown quantities because the target unknown quantity can be solved based on the known quantity and the system coupling equation, and particularly when the target unknown quantity can be directly solved based on one known quantity and one system coupling equation, the target unknown quantity may be considered to actually belong to the known quantity).
In this case, the number of unknowns in the set of unknowns after the removal process may be used as the number of unknowns of the corresponding subsystem, considering that the target unknowns have been removed from the set of unknowns.
Step S111d, regarding each unknown quantity set in which the target unknown quantity does not exist, taking the number of unknown quantities in the unknown quantity set as the number of unknown quantities of the corresponding subsystem.
In this embodiment, after determining whether the target unknown quantity exists based on step S111b, if there is at least one unknown quantity set without the target unknown quantity, the number of unknown quantities in the unknown quantity set may be directly used as the number of unknown quantities of the corresponding subsystem.
In the second aspect, it should be noted that, in step S120, a specific manner for determining the first target subsystem is not limited, and may be selected according to actual application requirements.
For example, in an alternative example, a subsystem with a degree of freedom as a target value may be determined as the first target subsystem.
For another example, in another alternative example, considering that the degree of freedom is determined based on the number of unknown quantities in the subsystem, especially in the above example, when the number of unknown quantities is directly used as the degree of freedom, in order to enable the effective solving process to be performed on the balance quantity of the first target subsystem to ensure the processing efficiency of the overall decoupling, in conjunction with fig. 6, step S120 may include step S121 and step S122, which is described in detail below.
Step S121, among the plurality of subsystems, determines the subsystem with the smallest degree of freedom.
In the present embodiment, after the degree of freedom of each subsystem is acquired based on step S110, the subsystem having the smallest degree of freedom may be determined among the plurality of subsystems.
Step S122, the subsystem with the smallest degree of freedom is determined as the first target subsystem.
In the present embodiment, after determining the subsystem with the smallest degree of freedom based on step S121, the subsystem with the smallest degree of freedom may be determined as the first target subsystem.
In this way, since the degree of freedom is determined based on the number of unknowns, particularly, when the number of unknowns is taken as the degree of freedom, the number of unknowns of the subsystem having the smallest degree of freedom is also the smallest, and therefore, the solution processing is facilitated and the efficiency is higher.
Optionally, the specific manner of executing step S122 to determine the first target subsystem with the smallest degree of freedom as the first target subsystem is not limited, and may be selected according to the actual application requirement.
For example, in an alternative example, if the minimum degree of freedom is 1, all subsystems with degree of freedom 1 are determined as the first target subsystem; if the minimum degree of freedom is 2, all the subsystems with the degree of freedom of 2 are determined as the first target subsystem.
For another example, in another alternative example, in order to enable an effective solving process for the balance of the first target subsystem to ensure the processing efficiency of the overall decoupling, step S122 may include the following sub-steps to determine the first target subsystem:
if the minimum degree of freedom is 1, determining a subsystem corresponding to the degree of freedom as a first target subsystem, wherein the degree of freedom is the number of the unknown quantities in the corresponding subsystem, and the unknown quantities in the subsystem are taken as the balance quantities of the subsystem (that is, only one unknown quantity in the first target subsystem is taken as the balance quantity of the subsystem);
if the minimum degree of freedom is 2, determining any one unknown quantity of two unknown quantities included in the subsystem corresponding to the degree of freedom as a balance quantity of the subsystem, and determining the other unknown quantity as a known quantity, wherein the degree of freedom is the number of the unknown quantities in the corresponding subsystem; the degree of freedom of the subsystem with the smallest degree of freedom is updated from 2 to 1, and the subsystem with the updated degree of freedom is determined as the first target subsystem (that is, if the degree of freedom of one subsystem is 2, it indicates that the subsystem has two unknown quantities, in this case, one of the unknown quantities may be used as a balance quantity, and the other unknown quantity may be determined as a known quantity (for example, in an example, the unknown quantity may be moved from an unknown quantity set to a known quantity set), so that the subsystem also has only one unknown quantity, and thus is determined as the first target subsystem).
In the third aspect, it should be noted that, in step S130, a specific manner of performing the solving process and the updating process is not limited, and may be selected according to actual application requirements.
For example, in an alternative example, in order to ensure that the balance quantities of different subsystems can be effectively solved, in conjunction with fig. 7, step S130 may include step S131, step S132, and step S133, which are described in detail below.
Step S131, aiming at each first target subsystem, determining a solving algorithm of the first target subsystem based on the composition of the energy flow equation set of the first target subsystem.
In this embodiment, after determining at least one first target subsystem based on step S120, for each first target subsystem, a solution algorithm for the first target subsystem may be determined based on the energy flow equations of the first target subsystem (e.g., the energy sources of the grid system and the heat grid system are different, and the corresponding energy flow equations are also different, so that the corresponding solution algorithms are also different).
Step S132, solving the balance quantity belonging to the unknown quantity in the first target subsystem based on the solving algorithm of each first target subsystem to obtain the value of the balance quantity.
In this embodiment, after determining the solution algorithm of each first target subsystem based on step S131, for each first target subsystem, the solution processing may be performed on the balance of the first target subsystem based on the solution algorithm of the first target subsystem. In this manner, the value of the balance of each first target subsystem may be derived such that the balance changes from an unknown quantity to a known quantity.
Step S133, updating the degrees of freedom of each of the first target subsystems.
In the present embodiment, after the value of the balance amount of each first target subsystem is obtained based on step S132, since the balance amount has been changed from an unknown amount to a known amount, the degree of freedom of the first target subsystem is also changed, so that the degree of freedom of each first target subsystem needs to be updated, such as reduced.
On the basis of the above example, considering that the degree of freedom of other subsystems may be affected after a balance amount is changed from an unknown amount to a known amount, in order to effectively update the degree of freedom of other subsystems, in an alternative example, in conjunction with fig. 8, step S130 may further include step S134 and step S135, which is described in detail below.
Step S134, determining whether the balance quantity of each first target subsystem has an association relation with other subsystems or not based on a system coupling equation included in the multi-energy coupling system.
In this embodiment, after obtaining the value of the balance amount of each first target subsystem based on step S132, it may be determined whether the balance amount of each first target subsystem has an association relationship with other subsystems based on a system coupling equation included in the multi-energy coupling system.
If the balance amount of the first target subsystem is related to the other subsystems, then the other subsystems may be processed based on the known amount and the system coupling equation, so that the degrees of freedom of the other subsystems may be changed, and thus step S135 may be performed.
Step S135, update processing is performed on the degrees of freedom of the other subsystems.
In the present embodiment, after determining that the degree of freedom of the other subsystem has changed based on step S134, the degree of freedom may be subjected to update processing.
Alternatively, the specific manner of executing step S135 to update the degrees of freedom of other subsystems is not limited, and may be selected according to actual application requirements.
For example, in an alternative example, whether the balance of the first target subsystem is associated with other subsystems may refer to whether the balance of the first target subsystem and the parameters of the other subsystems can form a corresponding relationship based on the system coupling equation. Based on this, step S135 may include the following sub-steps:
if the balance quantity of the first target subsystem is associated with the other subsystems, determining the value of the corresponding quantity in the other subsystems based on the balance quantity and the system coupling equation (for example, the system coupling equation may be an expression of the corresponding quantity and the balance quantity, and thus after obtaining the value of the balance quantity, the value of the corresponding quantity may also be obtained based on the system coupling equation);
if the corresponding quantity is a known quantity, then the degrees of freedom of the other subsystems are increased (indicating that the error is larger at this time) when the error (which may be, for example, an absolute value of a difference between two values) between a value determined by the corresponding quantity (i.e., a value obtained by solving the system coupling equation and a value of the balance as described above) and a known value (i.e., a value which is a known quantity itself, where the corresponding quantity is based on a known quantity formed by moving one of two unknowns of the subsystem with the degree of freedom 2 to a set of known quantities in the above example, the known value may be an initial value of the unknowns, and it is understood that each unknowns has one initial value) is larger than a preset threshold (which may be set according to the accuracy requirement and the efficiency requirement, for example, the preset threshold may be smaller as the accuracy requirement is higher, the preset threshold may be smaller as the efficiency requirement is higher, further calculation is needed, for example, the corresponding quantity is moved back to the unknown quantity set, so that the degree of freedom can be added, for example, the degree of freedom is added by 1);
if the corresponding quantity is an unknown quantity, the degree of freedom of the other subsystem is subjected to reduction processing (for example, since the value of the corresponding quantity can be determined, the corresponding degree of freedom is reduced, so that reduction processing, such as 1-reduction processing, can be performed).
In the fourth aspect, it should be noted that, in step S140, a specific manner for determining whether the decoupling of the multi-energy coupling system is completed is not limited, and may be selected according to actual application requirements.
For example, in an alternative example, the decoupling of the multi-energy coupling system may be considered to have been completed after the degrees of freedom of the multi-energy coupling system are reduced by a certain percentage.
For another example, in another alternative example, the decoupling of the multi-energy coupling system may be considered to be completed when the degree of freedom of the multi-energy coupling system decreases to a preset value. Based on this, in conjunction with fig. 9, step S140 may include step S141, step S142, and step S143, which are described in detail below.
And step S141, determining whether the current degree of freedom of each subsystem is greater than a preset value.
In this embodiment, after the degree of freedom of the first target subsystem is updated based on step S130, it may be determined whether the current degree of freedom of each subsystem (including the first target subsystem and other subsystems) is greater than a preset value.
If the current degree of freedom of each subsystem is less than or equal to the preset value, executing step S142; if there is a subsystem with the current degree of freedom greater than the preset value, step S143 is executed.
And S142, determining that the degrees of freedom of the subsystems meet preset conditions, and determining that the decoupling of the multi-energy coupling system is completed.
In this embodiment, after determining that the current degree of freedom of each subsystem is less than or equal to the preset value based on step S141, it indicates that the degree of freedom of the multi-energy coupling system has decreased to the preset value, and thus, it may be determined that the degrees of freedom of the plurality of subsystems satisfy the preset condition, thereby determining that the decoupling of the multi-energy coupling system is completed.
And step S143, executing the target operation at least once until the current degree of freedom of each subsystem is less than or equal to the preset value.
In this embodiment, after determining that there is a subsystem whose current degree of freedom is greater than the preset value based on step S141, it indicates that the degree of freedom of the multi-energy coupling system has not decreased to the preset value, and therefore, the target operation may be performed at least once until the current degree of freedom of each subsystem is less than or equal to the preset value, so that the decoupling of the multi-energy coupling system is completed.
The specific manner of the target operation is not limited, and in an alternative example, in combination with fig. 10, the target operation may include step S143a, step S143b, and step S143 c.
Step S143a, determining a second target subsystem among the plurality of subsystems based on the current degree of freedom.
In this embodiment, the manner of determining the second target subsystem may refer to the explanation of determining the first target subsystem in step S120, which is not repeated herein.
Step S143b, solving the balance quantities belonging to the unknown quantities in each of the second target subsystems.
In this embodiment, the method for solving the balance amount in the second target subsystem may refer to the explanation of the solving the balance amount of the first target subsystem in step S130, and is not repeated here.
Step S143c, after the solving process, performs an updating process on the degrees of freedom of each of the second target subsystems.
In this embodiment, after the solution processing is performed on the balance of each second target subsystem, since the number of the unknown quantities changes, the degree of freedom also changes, and thus the degree of freedom of each second target subsystem may be updated, and the specific manner may also refer to the related description above, which is not described herein again.
It will be appreciated that the above-mentioned preset values may be different, depending on the actual requirements. For example, in an alternative example, in order to solve the unknown quantity in each subsystem of the multi-energy coupling system, that is, to ensure that each parameter in the multi-energy coupling system is a known quantity, the preset value is 0, so that the current degree of freedom of each subsystem is 0, it can be determined that the decoupling of the multi-energy coupling system is completed.
On the basis of the above example, in order to facilitate understanding of the decoupling method of the multi-energy coupling system, the embodiment of the present application further provides a specific application example. The application example may be based on the system shown in fig. 1, and the specific calculation steps are as follows:
